MODELING OF NONEQUILIBRIUM ELECTRIC ARC PLASMA

Abstract

The submitted two-temperature model of the nonequilibrium electric arc plasma is distinguished from earlier known models due to the techniques for accounting of the radiation transfer. The absorption of radiation was considered by the method of partial characteristics (PCM). The necessary transport coefficients were calculated in view of the occurrence of two temperatures in the arc plasma. It was obtained good quantitative agreement of calculated arc characteristics with experimental data.
